AI Technical Summary

Benefits of technology

The solution reduces transition resistance and weight while simplifying connections and protecting electrical components from external influences, eliminating the need for external holders and achieving compliance with MIL standards.

Problems solved by technology

It is disadvantageous that each through-hole can only accommodate a limited number of cable lugs, for which there are also not uniform transition resistances owing to different starting torques.
When using angled elements made of aluminium, the oxide layer present in the connection region of the cable lugs disadvantageously has to be removed, for example by an additional mechanical operation.

Embodiment Construction

[0024]FIG. 1 is a schematic view of an earth connection 10 for electrically and mechanically connecting a plurality of earth wires (not shown) to a structure (not shown). The earth connection 10 comprises an angled element 12 and a housing 20. The angled element 12 is formed from an aluminium sheet and comprises a first and a second (not shown) fastening portion. The angled element 12 has a 90° bend in a region adjacent to the first fastening portion 15. The dimensions and the bend of the angled element 12 are dependent on the attachment position and load of the angled element 12. However, the bend can also have another suitable angle. Instead of an L angle, the bend can be formed in the shape of a Z angle.

[0025]The first fastening portion 15 is formed to be fastened to a structure, in particular to an aircraft structure. For this purpose, the first fastening portion 15 comprises a plurality of holes 15a. The connection between the first fastening element 15 and the structure is a r...

Abstract

An earth connection for electrically and mechanically connecting a plurality of earth wires to a structure, in particular to an aircraft structure, comprising an angled element which element is formed in one piece and is made of electrically conductive material, which comprises a first and a second fastening portion. The first fastening portion is fastened to the structure and the second fastening portion comprises a plurality of electrical connections for connecting the earth wires. The electrical connections comprise socket contact elements which are formed so as to receive pin contact elements of the earth wires.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims the benefit of the U.S. Provisional Application No. 61 / 594,429, filed on Feb. 14, 2012, and of the German patent application No. 102012202231.7 filed on Feb. 14, 2012, the entire disclosures of which are incorporated herein by way of reference.FIELD OF THE INVENTION[0002]The present invention relates to an earth connection for electrically and mechanically connecting a plurality of earth wires. The invention further relates to an aircraft comprising the earth connection according to the inventionBACKGROUND OF THE INVENTION[0003]It is known to fasten an angled element to a structure by means of riveted or screwed connections. The earth wires to be connected to the structure comprise cable lugs which are fastened to an associated fastening portion of the angled element using screws, washers and threaded nuts. For this purpose, there are through-holes for example inside the fastening portion of the angled element, wh...
